Summary

Brazil's internet registry, registro.br, publishes whois records in which the owner field is a mutable string: whoever controls the registry contact handles for an autonomous system can update the organization name, and third-party mirrors of those records diverge as they capture the field at different moments. The record for AS267241 is a textbook example. One mirror captured it as "AI BRAZIL TECHNOLOGIES & DATACENTER LTDA" with ownerid 15.644.251/0001-86 and responsible person Gessica M. Ferreira Silva (https://ip.cc/topic/asn/AS267241/). Another captured the same aut-num object — same ownerid, same creation date of 2018-03-01, same last-change date of 2020-09-25 — as "GMAES TELECOM LTDA EM RECUPERACAO JUDICIAL" with responsible person Cesar Roberto Silva Petrella (https://whois.ipip.net/AS267241). A third, and the BGP-derived name at bgp.tools, uses "GMAES TELECOM LTDA ME" (https://bgp.tools/as/267241).

What the CNPJ belongs to is not ambiguous. Brazilian corporate-registry mirrors consistently show CNPJ 15.644.251/0001-86 as GMAES TELECOM LTDA EM RECUPERACAO JUDICIAL, trade name Grupo Entel, opened 28 May 2012 and headquartered in Itajaí, Santa Catarina, with Cesar Roberto Silva Petrella associated (https://monitorcnpj.com.br/cnpj/15644251000186/). The phrase "em recuperação judicial" is the legal term for a company under court-supervised restructuring — Brazil's analogue to Chapter 11 — so the entity that formally holds the ASN has been in a creditor-supervised reorganization process. A procurement document published by the Tribunal de Justiça do Amazonas (TJAM) adds a second data point about that same CNPJ: its SICAF record appears there as "GMAES TELECOM LTDA" with the trade name "G20 DATACENTER & INTERNET", alongside a sanction record for temporary suspension due to total or partial non-performance of a contract (https://www.tjam.jus.br/index.php/documentos-licitacao/editais-avisos-erratas-e-docs/licitacoes-2023/pregao-eletronico-1/pregao-eletronico-n-046-2023/37991-pregao-eletronico-n-046-2023-suspensao-gmaes/file). Suspensions of that kind are administrative measures recorded during disputes or failures to perform; the document records the fact of the sanction, not a court's final merits ruling on any underlying dispute.

So where does the AI Brazil name come from? The separate corporate registry answer is that "AI.BRAZIL TECHNOLOGIES & DATACENTER LTDA" exists as its own company under CNPJ 45.908.107/0001-70, active since 5 April 2022, at Rua 1500, 820, Sala 2002, Edifício Sky Business Center, Balneário Camboriú/SC, with CNAE 6311900 — data processing, application service providers and internet hosting — as its principal economic activity (https://maiscnpj.com.br/cnpj/45908107000170-ai-brazil-technologies-datacenter-ltda). Its sole administrator, since 16 October 2023, is Gessica Maes Ferreira Silva (https://guiapj.com.br/consulta-cnpj/45908107000170). The AS267241 whois record ties the two threads together at the contact layer: the owner-contact handle GMFSI61 is registered to "gessica maes ferreira silva" with an e-mail address on a domain carrying the AI Brazil brand — and that handle was created on 19 October 2023, sixteen days after she became the AI.BRAZIL administrator, and last changed 4 August 2026 (https://whois.ipip.net/AS267241). In other words, one person sits at the administrative center of both the 2022 AI-branded company and the registry contact for the ASN formally owned by the 2012 telecom operator.

The network footprint

What does AS267241 actually do on the internet? The measurable answer is small. It originates exactly one IPv4 prefix, 45.232.28.0/22 — 1,024 addresses — and one observed more-specific, 45.232.31.0/24, within it (https://www.cidr-report.org/cgi-bin/as-report?as=AS267241&view=6447). It has a single upstream, AS264324 (GMAES TELECOM LTDA; BigDataCloud labels that upstream "BIT7NET TECNOLOGIA E SERVICOS LTDA" — aggregator naming diverges here), one observed AS path reading 7018 3356 53062 264324 267241, zero downstream networks and no direct peering agreements (https://ip.cc/topic/asn/AS264324/; https://bgp.tools/as/267241; https://www.cidr-report.org/cgi-bin/as-report?as=AS267241&view=6447; https://www.bigdatacloud.com/asn-lookup/AS267241; https://asrank.caida.org/orgs/21bcf5ab7f/as-core). CAIDA's AS Rank maps the organization "AI BRAZIL TECHNOLOGIES & DATACENTER LTDA" to a single member ASN, one prefix, 1,024 addresses and zero transit degree — the profile of a stub network (https://asrank.caida.org/orgs/21bcf5ab7f/as-core). Despite holding an IPv6 allocation, inetnum 2804:4a74::/32, the network originates no IPv6 prefixes in BGP (https://ipregistry.co/AS267241; https://ip.cc/topic/asn/AS267241/; https://www.bigdatacloud.com/asn-lookup/AS267241).

The routing-security details reinforce the picture. The IRR route objects covering 45.232.28.0/22 and 2804:4a74::/32 with origin AS267241 were not created by the network itself: the IPv4 object is a "Commcorp Telecom customer proxy route object that was created because no existing route object with the same origin was found", last modified 5 February 2025; the IPv6 object is a BR.Digital customer proxy, last modified 14 October 2024; both carry RPKI origin-validation state "not_found" (http://iad.robtex.com/as/AS267241.html). When transit providers create proxy route objects on a customer's behalf, it is usually because the customer never registered its own — a common practice among small resellers, and one more marker that AS267241 is operated as a hosting and transit customer rather than as an infrastructure operator with its own routing discipline.

The operating trace that does exist

The most concrete evidence of real business activity is public procurement. On 5 August 2025 the municipal government of Milagres, Ceará published a contract with "AI. BRAZIL TECHNOLOGIES & DATACENTER LTDA", CNPJ 45.908.107/0001-70, worth R$ 6,000.00, to host an e-SUS server in the cloud with daily file backup, described as located "in a modern data center" (https://www.milagres.ce.gov.br/contratos.php?id=569). e-SUS is Brazil's public primary-care health information system; municipalities routinely contract third parties to host its servers. A R$ 6,000 cloud-hosting contract is real, verifiable revenue — and it is the signature of a small hosting reseller, not of an AI compute operator.

The company's own website, aibrazil.tec.br, markets "AI Brazil MultiCloud" hosting and backup services aimed at Brazilian public-sector bodies, claiming servers located 100% in Brazil, daily backups, 24-hour monitoring and "more than 10 years of experience" serving municipalities (https://aibrazil.tec.br/). Two observations attach to that marketing. First, the AI.BRAZIL entity itself has existed only since 5 April 2022, so a "more than 10 years" claim predates its own registration by about eight years; a plausible reading — and it is only a reading, since the site does not document it — is that the claim refers to the earlier GMAES/Grupo Entel lineage under the same people (https://maiscnpj.com.br/cnpj/45908107000170-ai-brazil-technologies-datacenter-ltda; https://aibrazil.tec.br/). Second, the site names no facility, no capacity figure, no accelerators, no carrier list and no customers. As marketing, it asserts identity; as evidence of operations, it asserts nothing checkable.

What the evidence does and does not show

Everything the public record supports is consistent with this structure: an established regional telecom operator (GMAES, founded 2012, now in judicial recovery) formally holds AS267241 and its /22; the operator's routing and registry contacts have migrated to a person who also administers a 2022-founded company branded as an AI datacenter; that company sells cloud hosting and backup to small municipalities; and no public record — no peering, no facility disclosure, no capacity figure, no accelerator deployment, no customer-facing SLA from the named AI-branded company itself — connects the "AI datacenter" label to purpose-built

infrastructure.

The label sits on the name; the evidence sits on the reseller.

None of this is proof of wrongdoing, and this article asserts none. Registry name strings are legitimately mutable; sharing an administrator across two CNPJs is lawful; marketing claims of experience through a predecessor lineage may be accurate in substance. The finding is narrower and more useful: an "AI datacenter" identity in a company name is a claim, and in this case the observable record describes something materially different from what the name suggests.
